This invention relates to web feeding mechanism and while capable of generaluse f is especially designed as an improvement over my prior inventionon web-controlling and tension device, patented Aug.` 26, 1919, No. 1,314,178, on which I filed the applica- June, 1913, Serial No. 773,917. The principal object of this invention is to tion for Letters-Patent on the 16th day of,

provide a convenient4 co'nstruction" by 'v vh'iclgi'` the operator will be enabled toy feedthe ,web into the bite of the first printingcouple, while the press is stopped, by, simply tucking the free end of the web into the bite be-y tween the tapes and feed roller and turning the feed roller by handuntil thevfreb. is properly inserted between the printing and impression cylinders. This is advanta because the operator can have fulll control of the progress of the web` in feeding in, an yet thereafter the web will be positively forwarded both by the vprinting couple and the feed rollers and wi be under theirjoint control. Reference is to be had to the accompanyin drawings, in w'hichl ig. 1 is a diagrammatic View showing the pathy of the webthrough "the device which is the subject of `this invention and through the press; j l y Fig. 2 is a sideelevation of a paper feed device constructed in acoordancewith this invention; Y

Fi 3 is a sectional view of the Sarneon the llne 3--3 of Fig. 2; and j Fig, 4 is an elevation of the hand wheel on the feed roller.

In order to give the operator fulliconti'ol of the web so that hem'ay feed it iny at will by hand' when the press is stopped, the inven-` tion is shownV in connection with certain features illustrated rin my a-bovefidentiied application. The web passes over a bending roll 34 journalled in brackets 35 on the ous i, ed on the 8.111152. Thus each of the arms 52 j provided with a transverse operating pin 27 feed ofthe-press by a gear 34e. vThe web passesiuniderjalfeed roller 36 mounted on a A shaftfl() in beaingson the frame and their j overl a roll''B vwhichv is operatedfrom Y`the j press. 'Frolnthre the'webfgoes in the usual.`

way tothe impression andprinting cylinders `70l and .7.24 respectively.

On theshaft ofl the roll 38 is a spiral gear39 meshing with ay gear 40 on a shaft 4:1. Thissha-ft, byA a spiral gear 42, drives a j 4spiral gear ,4B Whichis loose on the shaft 10 y of the feed r0ller36. On this shaft is another gear 4:4.which drives two gears 45 on` shafts '46. Theseshafts are journalledin hinge'cup lieiari1`f1gs'47` and carry@J plurality .of tape pulleys 48. The feed belts or tapes i 49 pass from thesepulleys around,and con Atact with, thefeedrroller 36 and then over tightener pulleyS 6 V Each of 'the tightener pulleys is supported on anarm 52-loo`se on a transverse shaft 53.`

1 `Keyed to the shaft 53 are armsl 54. AEachrof which passes@y screw 56 into a nut 57 mount-K can be adjusted relatively to the shaft `53 V.for takingy up the `slack of its feed belt or VItape. For adjusting the entire` system of r tightener` pulleys simultaneously the shaft 53 is provided wthan arm 63 keyed to it. This has a nut 60 which receives an adjusting Iscrew 62 passing through a poppet 64 on If above identified patent.

` `r For the purpose of providing the hand fdabove mentioned the driving spiral gear 43 is provided/with a number of holes V24 in the `side adjacent to the clutch hub 25.. This clutchrhub 25 is securely fastened to the shaft 10 Vand contains a spring-pressed reciprocable, pin 26 adapted to engage the spiral gear 43 by entering one of the holes 24 inthe face 'thereon The spring-pin is 4.which projects through a slot 28 in the clutch hub and Aengages through a cam opening1 30 in the hub of a spring-actuated hand w eel 29. yThis hand .wheel hub is free to turn slightly on the clutch hub 25 and is normally with two each other numbered 3l and 33 having an;

held in extreme position by a spring 21.

against a fastening plate 22 on the end of the shaft. The cam opening 3() is provided projecting slots at right angles to inclined surface 32 beween them.

In operation when it is desired to disenffage the clutch, the hand wheel 29 is pressed rmly in opposition to the spring 21 against the face of the spiral gear. This brings the pin 27 out of the elongation 31 and into the main body of the cam opening 30 and then the hand wheel is turned in the direction of the arrow shown in Fig. 2 to bring the pin over into the slot 33. rIhis motion is assisted by the cam face 32. Thereafter the feed roller 36 can be turned in the same direction by the hand wheel without disturbing the relative positions of the parts for the reason that the cam slot has pulled' the pin 26 out of the hole 24 and caused the hand wheel to become fixed relatively to the shaft 10 while releasing the ear 43 from the shaft. It will be seen, t erefore, that the paper can be fed through by the operator even though the gear 43 is turning, and that if this gear is not turning the o erator can still perform this operation wit out turning an other portion of the machinery than t e feed roller 36. i

When it is desired to re-engage the feed roller with the power, a uick reverse motion of the hand wheel Wil allow the pin 27 to sprin back into the elongation 31 and engage gie shaft with the power through the springin of the pin 26 into one of the holes 24. T en the web is under the control of the forwarding rolls and the rinting couple and is fed positively by bot-li thereafter.

In this way by very simple mechanism the o erator is enabled to have full control of this feed roller whether the machine is running or not, and can feed the end of the webn at any time.

No claim is made herein to the web-feeding mechanism by itself apart from the clutch and associated elements as that constitutes the subject of a divisional application.

Although I have illustrated and described th only a. single embodiment of the invention I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish tobe limited to all the details of construction herein shown and described and especially not to the features which are also shown in my above identified application, but what I do claim is:

1. The combination with a printing press, of a feed roller shaft, a driving gear loose on the shaft and constantly driven from the press, a hand-wheel, a pin for connecting the hand-wheel with the gear, and means whereby when the hand-wheel is turned backwardly on the shaft, the pin will be withdrawn from the gear.

2. Ina printing press, the combination roller is fixed, a driving gear loose on the shaft, a hand wheel adapted t`o turn on the end of the shaft, a hub fixed to the shaft, means on the hub for connecting it with said gear, and means operated by theturning of the hand wheel for disconnecting the ear from the hub and xingthe hand W eel with respect to the hub, whereby the feed rolleroan be operated by the hand wheel in one direction.

4. In a rinting ress, the combination with a fee roller, o a shaft on which said roller is fixed, a drivin gear loose on the shaft, a hand wheel on t e end of the shaft, a hub fixed on the shaft, a spring pressed pin on the hub for positively connecting it with the gear, said hand wheel being movable axiall on the hub, and means whereby when the and wheel 1s moved towardv the ear and turned, the pin will be withdrawn rom the gear.

5. In a printing ress, the combination with a feed roller, ofp a shaft on which said roller is fixed, a drivin gear loose on the shaft, a hand wheel on t e end of the shaft a hub fixed on the shaft, a spring pressed pin on the hub for ositively connecting it With the gear, said hand wheel being movable axially on the hub, said hand wheel having a cam opening, and an operating pin on the spring pressed in pro]ecting into said cam opening and adapted to be moved ere y. 6. The combination with a feed roller shaft, of a driving wheel therefor, a hand-wheel, ieldin means for normally hol the and-Weel positively clutched to the shaft inde ndently of the driving wheel, said han -wheel being movable on the shaft, and means whereby motion of the hand-wheel in a longitudinal direction on the shaft will release thehand-wheel so that it can turn on theshaft, and its turning motion will release the driving wheel from the shaft.

` 7. The combination with a feed roller shaft. of a driving wheel therefor, a hand wheel, yielding means for normally holding the hand wheel positively clutched to the In testimony whereof I have hereunto set shaft, means for clutching the driving wheel my hand, in the presence of two subscribing to the shaft` said hand wheel being movable Witnesses.
